The package contains an example php script. This script demonstrates howto
authenticate with radius using PAP or CHAP (md5). If you authenticate with
Microsoft Radius servers then its not possible to use CHAP (md5). If you
would like to authenticate with Microsoft Servers you have to use
MS-CHAPv1 or MS-CHAPv2, but its more complicated, because you need md4,
sha1 and des to generate the right data. The enclosed examples demonstrate
all authentication-methods, including MS-CHAPv1 and MS-CHAPv2. To get the
MS-CHAP to work you need the mcrypt and
the mhash extension, starting with
version 1.2 of the package, the mcrypt extension is no longer needed.
